The machinability of titanium alloy is 20-40% of that of 45# steel, and if the hardness is less than HB300, strong knife sticking will occur; if HB>370, it is too hard to process, so it is best to process titanium alloys with a hardness of HB300-370. The main reasons affecting its machinability are briefly described as follows: 1) Gas impurities (oxygen, nitrogen and hydrogen, etc.) have a great influence on the machinability of titanium alloys, because titanium has high chemical activity and is easy to combine with gas impurities . When the temperature exceeds 600 degrees, titanium welding filler wire is oxidized to form an embrittlement layer, the so-called "tissue alpha layer"; hydrogen embrittlement occurs with hydrogen; hard and brittle TiN is formed with nitrogen at high temperature. 2) The plasticity of titanium alloy is small, which obviously affects its plastic deformation during cutting. The deformation coefficient of titanium alloy is only 1 or even less than 1, while that of ordinary carbon steel is about 3. When cutting, there is a very small contact surface between the chip and the rake face, so that the pressure and local temperature in the contact area are high, and the tool wears quickly. 3) Severe work hardening will occur when titanium alloy is processed. 4) When C>0.2%, the Grade 3 Pure Titanium Tube alloy will form hard carbides, which will cause abrasive wear of the tool and reduce the machinability

Types of pure titanium plates and their differences from other titanium alloys
Pure titanium plates can be divided into three types: hot rolling, forging and cold drawing. The specification of hot-rolled pure titanium plate is 5.5-250mm. Among them: 5.5-25 mm small pure titanium plates are mostly supplied in straight strips, often used as titanium alloys, bolts and various mechanical parts; pure titanium plates larger than 25 mm are mainly used for manufacturing mechanical parts or making seamless titanium Tube blank.
The physical and mechanical properties are different. Due to the difference in chemical composition and strength of titanium alloys, there are differences in physical and mechanical properties. The cold bending performance of the pure titanium plate is better, it can be used as a 180-degree hook, and the threaded titanium can only be used as a 90-degree straight hook; the weldability of the pure titanium plate is better, and ordinary carbon electrodes can be used. Use low-alloy electrodes; threaded titanium is better than pure titanium plates in terms of toughness and fatigue resistance.
The difference between Grade 7 Titanium Sheet and other titanium alloys: 1. The appearance is different. The appearance of pure titanium plate is smooth and round, without lines and ribs. The bonding force of titanium alloy is small, while the bonding force of other titanium alloys and concrete is large. 2. The composition is different. Pure titanium plate (first-grade titanium) belongs to ordinary low-carbon titanium, and other titanium alloys are mostly alloy titanium. 3 The strength is different, the strength of pure titanium plate is low, and the strength of other titanium is high. The plasticity of the titanium alloy is stronger than that of other titanium alloys, that is, the pure titanium plate has a large deformation before being broken, while the deformation of other titanium alloys is much smaller before being broken. 4. The physical and mechanical properties are different. Due to the difference in chemical composition and strength of titanium alloys, there are differences in physical and mechanical properties. The cold bending performance of the pure titanium plate is better, it can be used as a 180-degree hook, and the threaded titanium can only be used as a 90-degree straight hook; the weldability of the pure titanium plate is better, and ordinary carbon electrodes can be used. Use low-alloy electrodes; threaded titanium is better than pure titanium plates in terms of toughness and fatigue resistance.

Performance requirements of coating targets for hard coating
The performance requirements of the coating target for hard coating are mainly the requirements for the thermal conductivity, electrical conductivity and thermal expansion coefficient of the sputtering target. The temperature of the target increases due to sputtering, the higher the thermal conductivity, the faster the heat transfer, the better the evaporation effect of the target ions, and the higher the deposition efficiency; the smaller the difference between the thermal expansion coefficient of the target and the substrate, the more Well, to reduce the effects of thermal stress.
To sum up, the technical requirements for coating Zirconium Sputtering Target for hard coatings include target purity, density, composition and structural uniformity, etc.; the performance requirements are mainly for the thermal conductivity, electrical conductivity and thermal expansion coefficient of sputtering targets. Require.

Does Titanium Burn?
As we all know, the melting point of titanium is 1660.0°C, which is not easy to burn, but titanium is also easy to burn in the following environments:
1. When the titanium material is in contact with an open flame when it is in contact with air and samples, and the temperature exceeds 500 or 1200 degrees, the titanium will burn.
2. In dry chlorine gas, even if it is below zero, a violent chemical reaction will occur to form titanium tetrachloride, which will be decomposed into titanium dichloride and even burned.
3. Titanium materials may burn after contacting methanol, trichloroethylene, molten metal salt, and other media.
Therefore, Grade 3 Pure Titanium Sheet materials should avoid the above media during use.

Application of titanium rods and titanium alloy materials in the human body
Titanium Industrial Rod is a very common substance, and the purity of titanium sponge can reach 99.9%. The physical and chemical properties of titanium are very stable, it will not be absorbed by the human body, and it will not undergo chemical reactions when in contact with body fluids and drugs, nor will it be ionized, nor will it react with the musculoskeletal muscles of the human body, so it is called "biophilic". Metal". Because titanium is "biophilic", titanium can resist the corrosion of secretions in the human body and is non-toxic, and it is suitable for any sterilization method. Therefore, it is widely used in the manufacture of medical equipment, human hip joints, knee joints, shoulder joints, flank joints, skulls, active heart valves, bone fixation clips, biomedical titanium materials (basic materials: medical titanium rods, medical titanium plates, medical titanium Silk) is an important branch of medical materials science, mainly used to treat or replace human tissues, organs or enhance their functions, and is a new type of carrier material with high technical content and high economic value. When new muscle fiber rings are wrapped around these "titanium bones", these titanium bones begin to maintain the normal activities of the human body.
Therefore, the potential demand in the biomedical materials market is huge. As the first choice of biomedical materials - the demand for medical titanium and titanium alloys will also increase greatly, so it is imperative to increase the research and development of medical titanium materials.
